The uncertain nature of absences and their importance in species distribution modelling

  
Ecography, Vol. 33, No. 1. (1 February 2010), pp. 103-114, https://doi.org/10.1111/j.1600-0587.2009.06039.x

Abstract

Species distribution models (SDM) are commonly used to obtain hypotheses on either the realized or the potential distribution of species. The reliability and meaning of these hypotheses depends on the kind of absences included in the training data, the variables used as predictors and the methods employed to parameterize the models. Information about the absence of species from certain localities is usually lacking, so pseudo-absences are often incorporated to the training data. We explore the effect of using different kinds of ...

Abstract

[Excerpt] [:Forests ecosystems, climate change and conservation] [...] Despite their importance, we have lost approximately 1.3 % of the total forest area during the last decade, and although deforestation rates are decreasing, they are still high (data for the period 2000-2010 [...]). Nevertheless, fortunately, in some regions, such as Europe, we find an inverse trend with an increasing forest cover [...]. In Europe, 33 % of the total land area (215 million ha) are covered by forests from which more than half ...

Using n-dimensional hypervolumes for species distribution modelling: a response to Qiao et al.

  
Global Ecology and Biogeography, Vol. 26, No. 9. (September 2017), pp. 1071-1075, https://doi.org/10.1111/geb.12611

Abstract

Hypervolume approaches are used to quantify functional diversity and quantify environmental niches for species distribution modelling. Recently, Qiao et al. ([1]) criticized our geometrical kernel density estimation (KDE) method for measuring hypervolumes. They used a simulation analysis to argue that the method yields high error rates and makes biased estimates of fundamental niches. Here, we show that (a) KDE output depends in useful ways on dataset size and bias, (b) other species distribution modelling methods make equally stringent but different assumptions ...

 

Competition theory, evolution, and the concept of an ecological niche

  
Acta Biotheoretica, Vol. 31, No. 3. (1982), pp. 165-179, https://doi.org/10.1007/bf01857239

Abstract

This article examines some of the main tenets of competition theory in light of the theory of evolution and the concept of an ecological niche. The principle of competitive exclusion and the related assumption that communities exist at competitive equilibrium - fundamental parts of many competition theories and models - may be violated if non-equilibrium conditions exist in natural communities or are incorporated into competition models. Furthermore, these two basic tenets of competition theory are not compatible with the theory of ...

 

Do hypervolumes have holes?

  
The American Naturalist, Vol. 187, No. 4. (15 February 2016), pp. E93-E105, https://doi.org/10.1086/685444

Abstract

Hypervolumes are used widely to conceptualize niches and trait distributions for both species and communities. Some hypervolumes are expected to be convex, with boundaries defined by only upper and lower limits (e.g., fundamental niches), while others are expected to be maximal, with boundaries defined by the limits of available space (e.g., potential niches). However, observed hypervolumes (e.g., realized niches) could also have holes, defined as unoccupied hyperspace representing deviations from these expectations that may indicate unconsidered ecological or evolutionary processes. Detecting ...

 

A cautionary note on the use of hypervolume kernel density estimators in ecological niche modelling

  
Global Ecology and Biogeography (August 2016), https://doi.org/10.1111/geb.12492

Abstract

Blonder et al. (2014, Global Ecology and Biogeography, 23, 595–609) introduced a new multivariate kernel density estimation (KDE) method to infer Hutchinsonian hypervolumes in the modelling of ecological niches. The authors argued that their KDE method matches or outperforms several methods for estimating hypervolume geometries and for conducting species distribution modelling. Further clarification, however, is appropriate with respect to the assumptions and limitations of KDE as a method for species distribution modelling. Using virtual species and controlled environmental scenarios, we show ...

The past ecology of Abies alba provides new perspectives on future responses of silver fir forests to global warming

  
Ecological Monographs, Vol. 83, No. 4. (November 2013), pp. 419-439, https://doi.org/10.1890/12-2231.1

Abstract

Paleoecology can provide valuable insights into the ecology of species that complement observation and experiment-based assessments of climate impact dynamics. New paleoecological records (e.g., pollen, macrofossils) from the Italian Peninsula suggest a much wider climatic niche of the important European tree species Abies alba (silver fir) than observed in its present spatial range. To explore this discrepancy between current and past distribution of the species, we analyzed climatic data (temperature, precipitation, frost, humidity, sunshine) and vegetation-independent paleoclimatic reconstructions (e.g., lake levels, ...
